2. INSTALLATION

Connect the torch to the power source. After connecting electric power and compressed

air, the machine is ready for use. Please read the enclosed instructions on how to use the

central connector.

Power supply

Connect the machine to 3-Phase, 50 Hz, 400 V only.

Use with generators

SPLITFIRE, SPEEDFIRE and UPPERCUT are equipped with filters for use with mobile

generators. The generator should be of at least 15 kVA for SPLITFIRE, 22 kVA for

SPEEDFIRE and 27 kVA available exclusively for the plasma cutting system.

Air supply

Connect dry, clean and oil free compressed air to the filter regulator on the rear of the

machine and adjust to 4,5 bar for SPLITFIRE and 5 bar for SPEEDFIRE/UPPERCUT. When

cutting at lower amperage than 70 A with SPEEDFIRE/UPPERCUT it may be necessary to

lower the air pressure to 4,5 bar in order to get the best cutting capability. Don’t forget to raise

the pressure again if returning to amperage above 70 A.

SPLITFIRE SPEEDFIRE UPPERCUT

3. OPERATING INSTRUCTIONS

Check that the machine has been properly connected to power supply and compressed air

according to chapter 2, INSTALLATION.

Check that the torch is fitted with appropriate consumables for the job at hand.

Connect the earth lead clamp directly at the work piece, ensuring that a good contact is

obtained. If necessary, clean the surface from paint, rust, dirt, etc.

Cutting

Switch the machine’s main power switch on. The READY lamp will light and the fan

will start working.

Choose process power, 20-80 for SPLITFIRE, 20-100 A for SPEEDFIRE or 20-120 A

for UPPERCUT.

Manouver the torch in position for cutting or gouging.

Press the START-switch on the torch handle.

Air will flow for one second before the pilot arc strikes. The pilot arc will burn for

about 3 seconds. If contact with the work piece is not obtanined within this time, the

pilot arc goes out. Then make a new try.

To end the process, release the START-switch. The plasma arc goes out

instantaneously. Air will continue to flow for about 30 seconds.

NOTE! When the machine is not in use or is only working at long intervals, switch off

the machine. It contains mechanical components that should not be exposed to unnecessary

wear. It also protects against unvoluntarily firing the pilot arc.

N.B. Don’t use consumables for more than 80 A with the SPLITFIRE or 100 A

with the SPEEDFIRE. The result will be poor cutting capability.

5. MAINTENANCE

DAILY

Inspect and, if necessary, change the torch consumable parts.

Inspect and, if necessary, empty the moisture trap on the filter regulator on the rear side of the

machine. The trap is emptied by pressing the bottom sealing while compressed air is

connected. If cleaning the trap is necessary, completely unscrew the glass cup after

disconnecting compressed air.

Carefully inspect the hose assembly and torch body with regard to any leak or damage.

Never use a damaged torch.

EVERY SIX MONTHS

Disconnect the machine from compressed air and electricity. Remove the cover. Clean

the machine with dry, clean and oil free compressed air. Inspect cable connections and gas

system.

In unusually dirty environments this procedure should be carried out every month.

6. TROUBLE SHOOTING.

Thermal overload / Air supply failure

If the fan is working, but the green READY-lamp is not lit, the air supply is not

sufficient or the thermal overload protection is active. Check the compressed air supply. If the

machine is overheated, let it cool down while switched on until the lamp lights again. Then

the machine is in working order.

Malfunction

If the pilot arc does not strike:

•The safety switch of the torch is not closed. Check that the protective cup is

properly tightened.

•Check the air pressure on the filter regulator on the rear of the machine. The

pressure should be approx. 4,5/5,5 bar.

If the pilot arc is unstable:

•Check the air pressure on the filter regulator on the rear of the machine. The

pressure should be approx. 4,5/5,5 bar.

•The machine is working two phase. Check electrical supply.

Inferior cut quality or performance:

•Check the torch consumables. Replace if necessary.

•Inspect the torch body and hose assembly with regard to any damage or leak.

•Check the air pressure on the filter regulator on the rear of the machine. The

pressure should be approx. 4,5/5,5 bar.

•Check the earth lead connection. Place the earth lead clamp directly on the work

piece. If necessary, clean from paint, dirt, rust etc.

7. SAFETY INSTRUCTIONS

All endangerments through plasma cutting are related with the process itself. Endangerments

may occur due to:

High contact voltage

HV ignition

Electromagnetic interferences

Heat and light radiation

Gases, fumes and smoke

Noise

Hot metal and spatter

Handling of pressure cylinders

The Plasma Cutting Machine has been developed in conformity with following standards:

EN 60974-1 safety requirements for installations for arc welding and welding power

sources

Endangerment due to high contact voltage

Warning!

Before opening the plasma rectifier generally the input power has to be disconnected

physically from the mains (unplug mains cable)! Only advised personnel are allowed to

carry out any repairs to the machine.

Attention! Connect the work piece cable and earth the workplace before starting the

machine!

The power source is equipped with a cooling unit and there is an electric potential between

the housing and work piece in case the work piece isn't earthed and the machine is switched

on. Because of the high resistance of more than 10 kOhm in the coolant the contact voltage is

absolute not dangerous but sensible.

Special hints:

Connect power source only to correctly earthed mains socket with proper connected

safety conductor

Wear insulating protective clothing (safety shoes, leather apron, gloves), place torch

on insulated holder,

Make sure that they cutting area and plasma machine components are dry and clean,

arrange regular inspections.

Never short safety circuits.

Working under elevated electrical endangerment

This plasma cutting machine in conformity with valid standards (EN 60974) can be used for

operation under elevated electrical endangerment

The power source and the plasma torches are forming a safety-proofed installation

which can be separated only by using tools.

The patented design of the torch prevents electrical danger when the torch

consumables are disassembled.

Therefore the power source is marked with the S-sign and operation under elevated electrical

endangerment is allowed.

Attention! Always follow the local safety rules!
